Vasilisa

Vasilisa (ワシリーサ Washirīsa?, Russian: Василиса) is a character introduced in Toaru Majutsu no Index. A perverted woman obsessed with Japanese popular culture, she is the mediator of Annihilatus and the superior of Sasha Kreutzev, whom is often irritated to the point of violence of her superior's antics. She is disliked by Sasha due her sometimes childish behavior, her vanity on skin health care, and her weird interest in Japanese otaku culture. She frequently abuses her authority by trying to get Sasha into a "Magical Powered Kanamin" costume or other cosplay. Even in serious situations, it is difficult to tell whether or not is Vasilisa being serious, an example of when she gave Sasha an assumable emergency bag but later to be reveal containing a Magical Powered Kanamin’s dress. Despite this, her personality doesn't get in the way of her being a strong magician, being ruthless to her enemies as shown when she and Sasha fought Touma.
